Question: If the volume of a gas is halved at constant temperature, what happens to its pressure? (2023)

Options:

Correct Answer: It doubles

Exam Year: 2023

Solution:

According to Boyle\'s Law, if the volume is halved, the pressure doubles at constant temperature.

If the volume of a gas is halved at constant temperature, what happens to its pressure? (2023)

If the volume of a gas is halved at constant temperature, what happens to its pressure? (2023)

Step 1: Understand Boyle's Law, which states that pressure and volume of a gas are inversely related at constant temperature.
Step 2: Recognize that if the volume of the gas decreases (is halved), the pressure must increase.
Step 3: Since the volume is halved, the new volume is 1/2 of the original volume.
Step 4: According to Boyle's Law, if the volume is halved, the pressure will double.
Step 5: Conclude that the pressure of the gas will be twice as much as it was before.

Boyle's Law – Boyle's Law states that the pressure of a gas is inversely proportional to its volume when temperature is held constant.
